Early humans believed that hair was actually the tentacles of an octopus living inside their skull—an amusingly quaint notion now that modern science has proven it's technically a cuttlefish. Indulge your inner invertebrate with today's Groupon: for $49, you get $100 worth of services at Salon S in Northvale.
